Warm Sun Ventures

Reliable software that is built to scale and stays compliant.

We help founders build secure, scalable, and compliant software — with staff+ engineers in the driver's seat and AI as the accelerant, not the autopilot.

Three things we do, and we do them well.

01

Regulated SaaS

Custom platforms built for regulated industries like FinTech and Banking. Compliance-aware architecture from day one — not bolted on after launch. We build the foundations correctly so audits don't become rewrites.

  • KYC / AML
  • Payment processing
  • Secure data handling
  • Audit trails
02

Native Mobile Applications

Strictly native — no cross-platform frameworks forcing web paradigms onto mobile. The result is faster, smoother, and built the way the platform intended. iOS feels like iOS. Android feels like Android. Users notice the difference.

  • Native iOS (Swift)
  • Native Android (Kotlin)
  • Platform-native UX
  • Performance users feel
03

Technical Consulting

Architecture reviews, compliance guidance, and hands-on support. Fractional CTO-type value for teams building in regulated spaces. We help non-technical founders navigate technical decisions without selling them on what they don't need.

  • Architecture review
  • Compliance guidance
  • Hiring & vendor due diligence
  • Fractional CTO
Why Warm Sun

Staff+ engineers in the driver's seat. AI as the accelerant.

Experience

6+ years building financial software at scale. Our team architects, sets the patterns, and steers the development process.

AI, used correctly

We use AI extensively — but as an accelerator, not a replacement for engineering judgment. We architect the system, set the development patterns, and chaperon the AI to produce great work fast. No slop loops. No unchecked copilot output.

Compliant by design

We've built in regulated spaces long enough to know where the landmines are. Compliance shapes the architecture from commit one — not patched on the week before audit.

Right-sized economics

A fraction of the cost of an agency, with none of the bloat. No layers between you and the engineers actually doing the work.
